How Busy Professionals Can Train for an Ultramarathon

If you’ve ever found yourself juggling Zoom calls, deadlines, and school pickups while wondering how on earth you’re going to fit in training for a 50k, 100k, or even a 24-hour race, you’re not alone. One of the most common questions I get from prospective clients is:

“Can I train for an ultramarathon with a full-time job and family?”

The answer? Absolutely.

But it takes a shift in thinking, some clever planning, and a strong dose of self-awareness.

I’ve coached hundreds of ultrarunners, many of them full-time professionals, parents, or business owners, and I’ve also lived it myself. Here’s how we make it work.

1. Ditch the All-or-Nothing Mindset

Training for ultras isn’t about perfection, it’s about consistency. You don’t need 20-hour training weeks to succeed. Some of the most successful athletes I coach train 6–8 hours per week when life is hectic.

What matters most is doing what you can, consistently, and not letting a missed session derail your momentum.

Tip:

If you miss a long run, don’t try to ‘make it up’, just move on and focus on the next key session.

2. Train Smarter, Not Just Longer

The biggest gains don’t come from simply adding volume, they come from purposeful structure. For time-starved runners, every session must earn its place.

• Use back-to-back runs on the weekend to build endurance.

• Include moderate-intensity efforts midweek to develop efficiency.

One of my go-to tools? A 5% incline treadmill session at an easy aerobic effort. It simulates the muscular fatigue of ultra racing without smashing your body. Simple. Effective. Time-efficient.

3. Make Recovery Part of the Plan

Busy professionals are often tired before they lace up their shoes. Sleep, stress, poor nutrition, all take a toll. The key is adapting training to life load.

If your job has you up at 5am and managing back-to-back meetings, your body will interpret stress from training differently. As a coach, I monitor both training and lifestyle demands to avoid burnout or injury.

Guideline:

If you’re regularly waking up exhausted, your training might be doing more harm than good.

4. Master the Early Morning Run

For many, the early hours are golden. Fewer distractions. More headspace. A stronger sense of control. Morning runs also tend to be more consistent because life hasn’t had time to get in the way yet.

Not a morning person? It’s a learned habit. Start with just 20–30 minutes. Build the routine. Don’t aim for perfect, just aim for present.

5. Build Your Support Crew

Whether it’s a partner, friend, or group chat full of runners, support matters. Having people who understand (or at least respect) what you’re trying to do makes a big difference.

Your support team isn’t just there to cheer for you on race day, they help you stay accountable during training, and remind you why you started when motivation dips.

6. Fuel Like You Mean It

Nutrition is the often-overlooked pillar of training. If you’re working long hours, chasing kids, and training at dawn, you need to fuel like an athlete, not someone on a crash diet.

In longer events, those who’ve trained their gut to handle 90g plus of carbs/hour often outperform those who don’t. Just look at Matt Field, who I coach, he broke the British 24-hour record last year averaging 108g/hour of carbs. He practised that in training, not just on race day.

7. Make Time Count, Not Just Miles

Here’s the truth: not every ultra-finish requires a 100-mile training week. Many of the athletes I coach finish races and even qualify for international teams on training that fits around family, careers, and life.

What matters most is purpose, progression, and patience. The key is to build a plan that’s sustainable and tailored to you, not some copy-paste plan from the internet.

To train for an ultramarathon with a full-time job isn’t easy, but it is possible. And when you do it right, it’s one of the most empowering things you’ll ever achieve.

It’s not about being the fastest. It’s about being the most committed version of yourself, one mile, one early morning, one focused session at a time.

If this article resonated with you and you’re thinking about taking on an ultra challenge,  you don’t have to figure it all out alone. I’ve coached first-time ultrarunners, Elite athletes, finishers of some of the worlds toughest races, and  national record-holders, but the principles are always the same: structure, belief, and doing what’s right for YOU.
